WINDOW-SHADE ADJUSTER.

Patented Feb. 13, 1912.

Application filed March 24, 1511. Serial No. 616,761.

To all whom it may concern:

Be it known that T, llanuv ()orinsur, a citizen of the United States, re iding at Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful lmprovenumts in lVindow-Shadc Adjusters, of which the following is a specification.

This invention relates to that class of devices which are designed to let windowshadcs down from the top.

It is often desirable to open a window at the top, and yet, to have the lower portion screened. lint shades mounted upon rollers having bracket bearings pm'mauently fixed at the top of the windows. as usual, would prevent the free passage of air.

Therefore. the object oi this invention is to provide means for vertically adjusting the brackets and the shades supported thereby.

To this end, my invention consists in the construction and combination of parts forming' a window-shade adjuster, hereinafter more fully described and particularly set forth in the claim, reference being had to the accompanying drawings in which-- Figure I is a front View of a. window shade showing my adjusting device in serw ic. Fig. ll shows my invention in fragmentary, side elevation, partly in section. Fig. III shows a transverse section at line m of Fig. II. Fig, TV shows an extension rod and lug.

A rail 5, haviirg side flanges 6. forming a T-shapcd body, is to be secured by suitable screws 7, to the casing at each side of the window. Brackets 8, which may be of the usual form for shade roller bearings, are slidably mounted on the rails '5, their inward extending flanges 9, passingunder the rail flanges 6, to keep the brackets in standing position. The rails 5, should be long enough toextend from the top of the window down within reach of a person standing on the floor. A rod 10, 1S rigidly secured to each bracket- 8, and extends down through a lug 11, which is in line of the rail. and may be fixed thereto as shown. To the lower end of the rod 10, a box 12, is secured to carry a latch 13, and its spring 14. The latch is hun to oscillate in the box upon a pin 26, and 1S shaped with a book 15, to engage the lug 11. The springl t, actuatcs the hook normally into engagement A stop-guide 16. is mounted to slide upon the rail 5, like the bracket 9, and is provided with a binding screw 17, adapted to enter any one of the spot-holes 18, in the rod, and thereb be held rigidly to the rod.

The operation is as follows. A shade 19, being ll'l()llllt((l by its roller 20, in the brackcts S, the operator presses upon the lower ends of the latches 13, disengaging their hooks lit, from the lugs 11, then he lowers the rods 10, and the brackets thereon until the stop guides It), rest on the lugs .11. (orresponding spot holes 18, in the two rods being at the same distance from the brackcts, the rods will hold the curtain roller level. There may be a number of spot holes 18. in each rod, to set the curtain at any height desired. For use with very high windows, extension rods 21, Fig. IV, are provided with sockets to, engage the rods t0, in place of the. boxes 12, and these boxes are then .to be attached at. 23, to the rods 21. This requirns another lu e 24, to serve like the lug ll. .ecured in line of the rail 5, to the window casing, in any suitable manner, as by the screws 25. As these adjusting fixtures may be easily substituted for the common brackets, one reason for making the rods in sections is to keep all the parts short enough to be admitted to the United States mails so that the device may be supplied by a mail order business. This window shade adjuster being strong, light, ()fSllHplC construction and inexpensive, will economically serve a purpose of much advantage.

I claim,

1. Tn a window shade adjuster, T-shaped rails to be located at the sides of the Window: lugs located in line of the rails: shadehanging brackets slidably mounted on the rails; a. rod having spot-holes in it, secured to each bracket and fitted to slide through one of the said lugs; a box secured upon each rod; a latch and a spring, therefor mounted in each box and adapted to engage one of the said lugs; a stop-guide slidably mounted on each rail and adjustable along one of the said rods; and a binding-screw in each stop-guide, adapted to engage an i one of the spot-holes therein, the same lug being engagwl by the said latch to hold the shade in its normal position, and by the said stopg'uide to hold the shade when lowered. 2. In afiwindow shade adjuster, rails to be located at the sides of the window; a lug to be located in line of each rail; :1 shade-hang upon the rod, substantially as shown and 10 ing bracket mounted to slide on each rail described.

and provided with a, rod which extends In testimony whereof I aifix my signathrough the said lug; a spring latch mount ture in presence of two witnesses.

ed on the end of the rod and adapted to engage one of the said lugs; and e stop-guide HARRY OGLESBY. to enga e the same lug .lidably mounted Witnesses: on a ran and the adjacent rod, and means WM, P. LEAR, for securing this stop-guide at definite points ANNA G. SMILEY.
